Guest Post: How Our Government Is Supporting Green

November 28th, 2012 | by GBE FACTS

Government subsidies help aid an industry when it is not progressing fast enough in the free market. Generally, when new technology becomes available like green energy, it can take a considerable period of time before prices decline enough to where consumers find the technology affordable. The free market just doesn't work as fast as some governments would prefer, so they intervene, helping important technology like green energy until it becomes profitable for businesses quicker than it would through the free market.

GUEST POST: Choosing the Right Type of Renewable Energy

April 13th, 2012 | by GBE FACTS

You may believe wholeheartedly in renewable energy and the concept of sustainability that serves as the foundation stone. What kind of renewable energy in which you choose to invest, however, is quite another matter, especially if considering something like biomass. This guest post from the Enerfina in the UK might help with your understanding

Real Renewable Energy vs. Renewable Energy Credits

July 30th, 2007 | by Philip Proefrock

<p> <img src="/files/111/greenpower.jpg" alt="" width="211" height="300" align="right" />A couple of my friends have recently asked about the new renewable energy credit program that our local electricity utility, <a href="http://www.dteenergy.com/">DTE Energy</a>, is now offering. One friend asked me about it directly, and another raised the question on the state mailing list for the <a href="http://www.o2-usa.org/mi/">o2 Network</a>. There was an interesting discussion about the topic on the 02 list, and I've included some of the information that other people shared on that list in this article. </p> <p> In southeast Michigan, the local electricity company is DTE Energy. Although it has (or had) a number of business units exploring all manner of alternative energy production, DTE has been relatively resistive to including any renewable energy in its portfolio. Despite consumer demand for green energy, DTE has no plans to construct anything, and has been very resistive to connecting alternative producers to its grid. (This is the same company that <a href="http://cornellbox.livejournal.com/14869.html">fought against</a> <a href="http://www.michigansthumb.com/site/news.cfm?newsid=17333256&amp;BRD=2292&amp;PAG=461&amp;dept_id=571474&amp;rfi=6">connecting a wind turbine</a> installed at a local middle school from connecting to the grid.) </p> <p> Looking at the <a href="/guide/renewable_energy_credits_rec">renewable energy credit (REC)</a> program that DTE is offering, there isn't much to it. DTE is offering now has two options for residential customers. One is a premium of 2 cents per kilowatt-hour (kWh) on all electricity used. The other is to buy RECs in blocks of 100 kWh for $2.50 each (2.5 cents per kWh). These are supposed to come from in-state sources, to the greatest extent possible, but DTE has argued that there aren't many in-state sources available to them. </p> <p> Michigan's Pubic Service Commission &quot;<a href="http://efile.mpsc.cis.state.mi.us/efile/docs/14569/0206.pdf">Opinion and Order</a>&quot; (PDF) regarding DTE's program recognizes the comments and criticism about the program and how much (or how little) it will do to encourage the development of renewable energy production in the state of Michigan.</p>
